Description

一种耐磨耐腐蚀脱硫喷嘴的制备方法
技术领域
本发明属于无机材料制备领域，具体涉及一种耐磨耐腐蚀脱硫喷嘴的制备方法。
背景技术
脱硫喷嘴用于燃煤电厂烟气脱硫，除去燃煤电厂烟气中的二氧化硫及部分污染环境的气体。燃煤电厂的烟气和燃煤联合循环中燃气(供燃气轮机燃用)都有一项共同任务，即脱硫除硝(当然还有除尘)。电厂排出的不经脱硫除硝的烟气直接污染大气环境，而联合循环的燃气不经净化处理则会祸害燃气轮机的热端部件.其排气也会污染环境。
脱硫喷嘴是火电厂脱硫吸收塔中的关键设备，它具有形状复杂，曲面较多，成型困难、工作环境腐蚀性大等特点，这使得研制一种耐磨耐腐蚀喷嘴成为必须。当今吸收塔中的喷嘴多采用石膏模成型，运用这种方法制作的喷嘴，尺寸准确度低，产品均一性差，耐磨性差、强度不高。
专利CN201210378592.1公开了一种氮化硅耐磨部件是由氮化硅烧结体形成的，该氮化硅烧结体含有以其氧化物计2～4质量％的用作烧结助剂的稀土元素、以其氧化物计2～6质量％的Al组分、及2～7质量％的碳化硅。该氮化硅烧结体具有1％或更低的孔隙率、800～1000MPa的三点弯曲强度、及5.7～6.6MPa·m1/2的断裂韧度。根据该结构，即使使用金属氮化方法制造的便宜的氮化硅粉末，也可以提供一种氮化硅耐磨部件及制造该部件的方法，该部件具有可与普通氮化硅烧结体相比或更高的机械强度、高的抗磨损特性和滚动寿命，且具有出色的可加工性。
专利CN201410004180.0公开了一种氮化硅复相结合碳化硅砖，包括以下重量百分比的组分：43～80％的碳化硅砂、5～19％的工业硅、3～15％的二氧化硅微粉、10～20％的氮化硅、0.5～3.5％的转化剂、0.5～4％的增韧剂、0.5～3％的结合剂和0.1～1％的添加剂。同时，本发明还公开了上述陶瓷耐火材料的制备方法。本发明提供的陶瓷耐火材料具有新颖性、创造性、先进性和实用性，且耐磨损，抗剥落，抗酸碱能力强，对整体炉衬的匹配、延长整体炉龄起到相当大的作用；本发明制备方法科学简单，制作过程中利用空气中的氮气和其他氮化物作为烧成保护气体，而将空气中的氧气排出提高了局部含氧率，对自然环境有益无害，适合大力推广。
专利CN201220440687.7公开了一种电石炉出液口流槽，所述出液口流槽包括内衬和托槽，内衬为氮化硅结合碳化硅材料，内衬镶嵌在托槽内。该实用新型所述的电石炉出液口流槽，取消了通冷却水的结构，避免了冷却水泄漏的危险，内衬砖采用氮化硅结合碳化硅材质制作，这种材料具有耐高温、耐冲刷、使用寿命长等优点。氮化硅结合碳化硅内衬砖采用振动压机压制而成，保证产品密度和均匀性，提高了产品的抗热震性和耐磨性。
